Atenolol is a beta blocker medication primarily used to treat high blood pressure and heart-associated chest pain. Although used to treat high blood pressure, it does not seem to improve mortality in those with the condition. Other uses include the prevention of migraines and treatment of certain irregular heart beats. It is taken orally (by mouth) or by intravenous injection (injection into a vein). It can also be used with other blood pressure medications.

“Atenolol is a beta blocker; that is, an antagonist of the β-adrenergic receptors. It is specifically a selective antagonist of the β1-adrenergic receptor with no intrinsic sympathomimetic activity (i.e., partial agonist activity) or membrane-stabilizing activity. However, the preferential action of atenolol is not absolute, and at high doses, it can also block β2-adrenergic receptors.”
